Product Information
Part number 51317057415 is a brand-new, unused Genuine BMW trim component. Window-related trim can deteriorate with age and exposure to weather, requiring replacement to maintain proper sealing, appearance, and function.
Components such as seals, corner mouldings, window guides, window lifters, regulators, and the glass itself may require replacement due to excessive wear or failure. This Genuine BMW replacement provides the correct fit, finish, and function for the intended application.
Back Glass Seal
A back glass seal is a rubber weatherstripping component that surrounds the rear windshield. It creates a watertight and airtight barrier between the glass and the vehicle body, helping prevent water leaks, wind noise, and dust intrusion. A properly fitted seal also helps secure the glass and contributes to the vehicle's structural integrity.
Back Glass Seal Failure Symptoms
Water leaks: Moisture entering the rear cabin or trunk during rain or car washes.
Increased wind noise: Drafts or excessive noise caused by a worn or loose seal.
Visible deterioration: Cracked, brittle, shrunken, or separated rubber that can no longer seal or support the glass properly.
